There's a new Yahoo Photos Web site in closed beta right now. By June 21, Yahoo plans to post it on photos.yahoo.com. I got access to a very buggy preview, and with Google's Picasa Web Albums fresh in my mind, took it for a spin.
Yahoo Photos is a joy to use. While not perfect, it offers a superior experience to most photo sites.
For example, the upload tool, which runs inside a browser window, allows you drag photos, or entire folders, into it. It previews your images, tells you how long it's going to take to upload them, and allows you to down-sample the images to save bandwidth.
Yahoo owns another photo site as well: Flickr, the photo sharing site favored geeks. The Flickr influence in Yahoo Photos is evident in the tagging features. Unlike Flickr, however, you can safely ignore tagging in Yahoo Photos and still have a good experience. The primary organizational mode of Yahoo Photos is albums, and selecting photos for inclusion in albums, and organizing them within albums, is extremely easy. Yahoo Photos also has a clever "Smart Album" feature, which automatically puts photos in albums when they meet certain criteria (for example, if they have specified tags).
